vSpecification forming part of Letters Patent No. 39,169, dated July 7, 1863.

lo all tvhom it may oonoem.

Be it known that we, ISRAEL PEUX, of

.Southold,in the county ot Suffolk and State" of New York, and W. H. H. G-LovER, of the city, county, and State of New York, have in- ,a .vented a new an'd. Improved Skimmer for 0ils and other Liquids; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part ot' this specification, in whi'ch- Figure l represents va vertical central sec` Y .F ig. 2 is' a plan or top' still, lthe clear good liquid being in the middle.

l.The object ofthis invention isto drain oti the olea-r' liquid from the middle, clear from the scum on the top and from the dregs on the bottom. Theinvention consists. in the employment u, or'use of a shallow saucer-shaped vessel provided with one or more floats, and with a pipe leading from its lowestpointto the barrel or other vessel which is intended to receive the 'oil'or other liquid, said. pipe being` sustained by one or more oats in such a manner that the saucershaped vessel can be adjusted to f o'at en a-level'with the surface of the clear liquid u'nder the scum. and above. the dregs, the vessel being balanced by the oat or floats attached toit, and "the pipe being sustained by the float or oats which aresecured to thej same, and that the clear liquid drains oil' through said pipe until the saucershaped ves# sel' settles downon the dregs at -or near the 4bottom of the still or tank.' y

To enable others skilled in tlie art. to make and use our invention, we will proceed to describe it. with reference to the drawings.

A represents a saucer-shaped vessel, made f of tinned sheet-iron or anyother suitable ma-` t terial, and provided with three (more or less) i lrings,a which areintendedtp receivethe'ioats .other -suitable material, in the Aform ot' cones, or in any other desirable form orshape, and they are provided with openings b,'.which are closedhy stoppers. v They aresecured-to the lrings by small projections or lugs 'c onl .their to catch un'der theripgs and retainsaid floats .rm'ly in 4their places.y The'vessel A is provided with a centval-openipg, d, and with a pipe, C, ofindia-rubber 'or other suitable material,is firmly secured. One or more tloats, D, made similar to the tloats B, are intended to sustaiuthe pipe when the skimmer is put up .for use. The vessel A'is placed into thetank or 'still containing the oil or other liquid to be skimmed, and it is .balanced by means -of 'the floats B, so that itsinksdown level with the surface ot' .theclear liquid and below the scum. In order to obtain the correct-position ot' the vesselv A, the iioats B may be partially filled with shot or other 'heavy ma-` terial. The pipe-Opasses ott' through a suitaorder to prevent the pipe from dragging down the vessel Aits weight is balanced by thel tioat or Boats D, which .may also be'partially of the vessel A is constantly kept below-the surface of the clear liquid,and the scum which floats on the surface of T the liquid is not permitted to pass down .through said opening.

tity of the liquid in the tank diminishes the vesselA A vsettles down until it reaches, the dregs at or near the bottom.- These dregs, being' of greater dens'ityor specific gravity than the clear liquid, sustain the vessel A and prevent it sinking down to such a level that -some of the impuritiesjshould. find their way to the pipe C. The clear liquid is thus drained or still.

Our skimmer is particularly applicable to draining ott' the oil obtainedby boiling lish or other similar material, but it can also be usedv with advantage for other `liquids which,oin beingheated, raise a scum.

B. These Heats'. are madeot'sheet metal or,

sides, which' pass down thro'unhnotchesv in vthe rings, and, by turning the tioats, are made' short tubular projection, towhicli a flexible v ble stufting-box in the side of the still, and in' filledwith shot or-other suitable -1naterial. By these means the opening" d inthe bottoml The clear vliquid drains oft',vandF asthe quam" o", and the impurities are retained in thetank.

s It remainsto remark that the depthto 'it-'hielt the vessel A sinks can 'be regulated by means the saueer A and pipe G, substantially in the 2l .l I 1 39.169

of one or more sliding weights .arrn ged onY a. manner and for the purpose. herein shown and l rod op rods in such a ma'nner that by shiftn g said'weght'or weights either the iloat D is depressed, leasing the skimmer free to r1se,or

-viee versa.. v

What we claim as nemend-desire to secure by Letters Patent, is l The combination of the Hoa-ts B B B D with described.
